Installation Instructions

Tools Required:

• 1/2-inch Wrench
• 3/8-inch Wrench
• #2 Phillips Head Screwdriver
• Vacuum Cleaner (optional, for cleaning dust)
• Towel or Absorbent Cloth

Procedure:

1. Prepare the Refrigerator: Carefully pull the refrigerator away from the wall to access the rear panel.
2. Disconnect Power: Unplug the refrigerator from the electrical outlet. This is a critical safety step.
3. Turn Off Water Supply: Locate and turn off the main water supply valve to the refrigerator. This is typically found under the sink or behind the refrigerator.
4. Manage Water Spillage: Place a towel or absorbent cloth on the floor directly under the water inlet valve to catch any residual water when disconnecting lines.
5. Disconnect Inlet Hose: Using a 1/2-inch wrench, carefully unscrew the water supply hose from the existing water inlet valve.
6. Remove Rear Access Panel: Locate and remove the six Phillips head screws securing the lower back panel of the refrigerator. Set the panel and screws aside.
7. Remove Old Valve:
   • Unscrew the water valve holder from the refrigerator frame.
   • Identify the black C-clip on the bottom hose outlet of the valve. Slide this clip out and retain it for reuse.
   • Using a 3/8-inch wrench, push the white security ring up on the outlet hose connection and carefully remove the outlet hose from the valve.
   • Reach inside and unplug the electrical connector from the water valve. Press the tab on the connector to release it.
8. Clean Area (Optional): While the panel is off, use a vacuum cleaner to remove any accumulated dust from the back of the refrigerator for improved airflow.
9. Install New Valve: Reverse the removal steps to install the new LG 5220JB2010A water inlet valve.
   • Connect the electrical plug to the new valve until it clicks securely.
   • Attach the outlet hose to the new valve, ensuring the white security ring is pushed down to secure it, and reinsert the black C-clip.
   • Secure the new water valve holder to the refrigerator frame with its screws.
   • Reconnect the main water supply hose to the new valve using the 1/2-inch wrench. Ensure a tight, leak-free connection.
10. Restore Rear Panel: Reattach the lower back panel of the refrigerator using the six Phillips head screws.
11. Restore Water and Power: Turn on the main water supply to the refrigerator. Check for any leaks around the valve connections. Once confirmed leak-free, plug the refrigerator back into the electrical outlet.
12. Test Operation: Allow time for the ice maker to cycle and the water dispenser to prime. Test both functions to ensure proper operation.

Operation

The water inlet valve operates automatically, opening to allow water into the ice maker for ice production and into the dispenser when the water lever is pressed. It closes to prevent continuous water flow once the required amount of water has been dispensed or the ice maker fill cycle is complete.

Maintenance

• Regular Inspection: Periodically check the area around the water inlet valve for any signs of leaks or corrosion.
• Water Filter: If your refrigerator uses an inline water filter, ensure it is replaced according to the manufacturer's recommendations. A clogged or faulty filter can affect water pressure and potentially strain the valve.
• Cleaning: Keep the rear of the refrigerator clean and free of dust to ensure proper ventilation and prevent debris from affecting components.
